To all whom it may concern:

Be it. known that we, OsoAn LIED'IKE and JOHN M. BIEN, citizens of the United States, j

and residents of Newark, countyof Essex, and State of New J ersey,have invented oer:

tainnew and useful Improvements in Sash- Lockin Bars, of which the follow ng s specificztion.

This invention relates to and has for its cheap and easily constructed lockmg bar adapted for use, for example, with a sash which may be bodily displaced from its 0rdinary position in the frame and rotated to and held in any desired 10981131011.

Such windows may be used in a variety of places and in any buildings or construction, but are more particularly adapted for use in rooms such as sleeping porches or sun parlors where it is desired to obtain a maximum of ventilation and in which it is de sirable that the sash may be readily closed and held firmly and securely in its closed position as well as in all adjusted posltions.

Such window sashes are preferably displaceable outwardly from the building so that they project therebeyond and when so projected can be rotated into any deslred position. With a room, as, for example, a sun parlor, equipped with sashes of this character it all the sashes outwardly and to turn them into the position which, with the prevailing breeze, secures the best conditions of ventilation and circulation, such position can be firmly locked and held and can be changed into other positions and locked there with a minimum of exertion, and it is, of course, possible with the window so constructed to readily obtain access thereto on both faces so that the same may be washed on both sides without personal inconvenience or danger. The entire window space can be made available with the sashes completely open, and there is no sliding of sashes behind one another, or other cutting down of available openings.

In the drawing forming part of this spec ification and wherein the same reference numerals are uniformly used to designate the same parts throughout, Figure 1 1s a perspective view of a sash in its frame, parts being broken away for the purpose of clear sash locking bars illustration and the sash being shown pro- .moved into the deslred position and the bar jected outwardly and placed substantially object to provide a simple,

the sash at 15. prises anotched bar 16, the notches 17 being readily becomes possible to project and the sashes in,

parallel to its frame. Fig. 2 is a View in perspective of a locking means, and Fig. 3 is a transverse sectio al view of the window shown in Fig. 1. j

Reference character 10 is applied to des ignate what we which takes the and the window place of the ordinary sash,

frame isshown at 11. Such frame is preferably cut away on the sill, as

indicated at 12, though the cut away may be in the sash itself, and there is received in such cut away portion a link 13 pivoted 1n theframe at 14 andpivoted in the sash have termed a sash, and

at15,a"nd at the upper end there is a similar link 13 pivoted in the frame at 14 and in The locking means complaced preferably opposite one another, and the same is secured to the sash by means of a bracket 18 and the bar 16 is preferably provided near the bracket 18 with a hinge joint 19. On the window sill is a notched plate 20,

. the notches thereof being of a slze to receive the portions 21 of the bar 16 between the notches 17 and to hold the same in a manner which will be readily understood. The looking member 20 is and is preferably arranged on the sill in substantially the manner shown, the end 22 thereof being farther to the front of the frame than the opposite end 23 so as to form substantially a quadrant of a circle with one end directed outward.

The operation of the device will be readily understood from the foregoing. The sash, when closed, rests against the stops 24 in the frame, the members 13 and 13' being received in slots provided therefor, either in the sash or in its frame, as may be considered preferable. hen the sash is pushed outwardly it is supported by the links 13 and 13 and may be turned on the pivots 15, 15 to any desired position, and when so turned may be locked by inserting the bar 16 in the desired notch in the plate 20, which serves to hold the member 16 both against inward and outward movement and also against rotation, the part 21 of the bar 16 fitting closely in the notches in the arcuate member 20. When it is desired to change the adjustment of the sash or to swing it to a different position, the bar 16 may be lifted, this being permitted by the provision of the hinged joint 19, the sash turned. and

preferably arcuate in form 16 replaced in co-action with the plate 20 and in the proper position to bring about the proper adjustment.

It is to be understood that While we have illustrated the preferred embodiment of our invention, that nevertheless the same is to serve only for the purpose of affording a clear understanding of our invention and Having thus described our invention, what we claim is:

1. A notched locking bar for a movable sash pivotally secured to the sash at the lower end thereof and having a hinge oint between its ends, and an arcuate notched member adapted to be secured to the window sill and to receive notched portions of said bar andthereby hold and lock the sash in position, said arcuate locking member being placed with one end directed substantially longitudinally of the window sill and the other end directed outwardly.

2. A locking bar for a movable sash, said bar being pivotally secured to the sash at the lower end thereof and provided with a hinge joint near its pivotal mounting, and said bar having opposite substantially vertical notches in its sides, and an arcuate member having notches in its upper surface and adapted to be placed on the window sill and to receive the notched portions of said bar in its notches and thereby hold and lock the sash in position, said arcuate member being placed with one end directed substantially longitudinally of the window sill and the other end directed outwardly.

In testimony that we claim the foregoing, we hereto set our hands, this 24th day ofMay, 1917.
